Some further relations between unperturbational and perturbational dual optimization problems

The paper introduces and studies two new concepts of ‘the perturbational dual problem corresponding to an unperturbational dual problem’. The first one is based on the primal value function and the second one is defined for primal problems with target sets. For both concepts, the relations between some main perturbational dual problems and the perturbational dual problems corresponding to some main unperturbational dual problems are shown.
